High Efficiency Low Vibration Screening Machine for Aggregate
Processing
Product Introduction
The process of dividing fragmented materials into different
particle sizes through one or several layers of screening surfaces
is called sieving. A screening machine is a vibrating screening
mechanical equipment that uses the relative motion between bulk
materials and the screening surface to allow some particles to pass
through the sieve holes, and divides materials such as sand,
gravel, and crushed stone into different levels according to
particle size. The screening process of a screening machine is
generally continuous. After the screened raw materials are fed onto
a screening machine (referred to as a sieve), materials smaller
than the size of the sieve holes pass through the sieve holes and
are called undersized products; Materials larger than the size of
the sieve are continuously discharged from the sieve surface, known
as products on the sieve.
Product Advantages
The working part of the drum screen is a cylindrical or conical
screen cylinder, which is equipped with a rotating shaft along the
axis of symmetry of the screen cylinder. The entire screen rotates
around the axis of the cylinder, and the axis is generally
installed at a small inclination angle. The conical surface sieve
cylinder is installed horizontally, and the material is fed into
the small end of the cylinder and lifted up with the rotation of
the sieve cylinder. When it reaches a certain height, it falls down
by gravity, and the fine grade material passes through the sieve
holes on the working surface of the cylinder, while the coarse
particle material is discharged from the other end of the cylinder.
This continuous upward and downward movement achieves material
screening. The rotational speed of the cylindrical screen is very
low, the operation is stable, and the power balance is good.
However, its sieve holes are prone to clogging and deformation,
with low screening efficiency, small working area, and low
productivity. It can be used for screening and dewatering coarse
and medium materials. Mineral processing plants rarely use it as
screening equipment.
Simple and easy to maintain structure
Some models have simple structures, easy to disassemble and replace
screen surfaces, and are convenient for daily use and maintenance.
And screening consumes less electricity per ton of material, saving
operating costs.
Wide applicability
Can handle various materials such as moisture and viscosity, such
as mesh screens suitable for damp materials, cylindrical screens
have no requirements for high moisture and coal slurry, and are not
sticky or blocked; It is also widely used in various fields such as
mining, chemical industry, food, etc., to meet the needs of
grading, impurity removal, filtration, dehydration, etc.
Outstanding features, such as efficient and fast experimental
screening machine, simple operation, accurate and reliable results;
Fixed screens do not require power and have low cost; Roller screen
does not block the screen; The resonance screen consumes less
power, etc.
The screening machine utilizes the size and quality differences of
materials, as well as the varying settling velocities of liquids.
Small materials settle to the bottom of the tank while larger
materials settle. A grading screen is a device that uses a spiral
to push materials upwards and then mechanically screen them. It can
filter the materials in the mill according to their grades, and
finally screw larger materials into the feed inlet of the mill
using a spiral blade to overflow the filtered small materials from
the overflow pipe. The base of the grading screen is made of
channel steel, and the body is welded from steel plates.
